For the pull, I attached a little piece of wrapped candy to a string with tape.
I taped it inside as well.
...and (called in reinforcement) and we glued these to the body of the tube.
Fill it with candy (you can fill it before you wrap it all the way up and close the top off too, or I just left the tops open.
We added a little 'pull me in case of emergency tag' and a string (via two holes on the side) to hang these in all the boxes.
